It's safe to say the newest chapter of El Clasico won't be forgotten for a very long time.

Arguably the world's greatest rivalry, Real Madrid vs. Barcelona didn't even come close to disappointing—at least if you're a neutral fan—at the Bernabeu on Sunday night. The visitors eventually escaped with an epic 4-3 victory on the back of a Lionel Messi hat-trick, climbing to within one point of both Atletico Madrid and Real Madrid atop the La Liga table.

Following the match, the superstar Argentine discussed Barca's victory, which was translated to English courtesy of the club's official Twitter feed:

Unfortunately, for as breathless and scintillating as the always-legendary match turned out to be, it was draped in just as much controversy. Referee Alberto UndianoMallenco sent off Sergio Ramos in the 63rd minute and handed out three penalties, including two in the final half-hour that helped Barcelona erase a 3-2 deficit.

Many of the post-match talking points, unsurprisingly, surrounded the ref's decisions rather than the play on the pitch. Barca defender Gerard Pique talked to reporters about his displeasure in that fact, via beIN Sport's TancrediPalmeri:

Piqué: "We live in a country where after such a spectacular game we speak about the referee"

Most believe that only the third and final penalty—where Andres Iniesta was crushed in between Dani Carvajal and Xabi Alonso as a short-sided Madrid was attempting to stay even in the final minutes—was the one that should have been awarded.

Controversy certainly marred this particular match, but there is only more to come. Not only are there nine more thrilling matches as both squads jockey with Atletico Madrid for position at the top of Spain, but we still have another Clasico left in the Copadel Rey final.
